Lucky Lanes Bowling Alley is putting this design on its roof. Enter the volume of this design in cubic feet.

Explanation:

The block on top has length, width and height of 4, 4 and 20-4 = 16.

The volume of this block is 4*4*16 = 256 cubic feet.

The volume of the block down below is 160 cubic feet because 10*4*4 = 160.

The total volume is therefore: 256+160 = 416 cubic feet

c) the median for town a 30" is greater than the median for town b 25"

step-by-step explanation:

town a, median = q2 = 30

town b, median - q2 = 25

so the median for town a 30" is greater than the median for town b 25"

an = 22 + (n-1) *6

110 seats

step-by-step explanation:

an=a1+(n-1)(d)

a1 = 22   this is the first item in the sequence

d =6   this is how the sequence goes up

a)   an = 22 + (n-1) *6

b) a12 = 22 + (12-1) *6

    a12 = 22+11*6

  a12 = 22 +88

  a12 = 110
